The role of the Roper in chiral perturbation theory
(Elsevier B.V., 2011-11-01)
We include the Roper excitation of the nucleon in a version of heavy-baryon chiral perturbation theory recently developed for energies around the delta resonance. We find significant improvement in the P(11) channel. (C) ...

Decay of accelerated protons and the existence of the Fulling-Davies-Unruh effect
(2001-10-08)
A theoretic-oriented strategy was taken to address the weak decay of uniformly accelerated protons. The decay of uniformly accelerated p+'s was analyzed using standard quantum field theory (QFT). It was shown that the FDU ...

Dynamo effects and geometrical origin of the alpha term in affine theory of gravity
(Maik Nauka Publishing / Springer SBM, 2017-12)
Dynamo effect is considered in the context of an Unified field theoretical model based in affine geometries. We show that there exists an analog “α-term” in the equations that has a purely geometric origin, in sharp contrast ...
alpha alpha scattering in halo effective field theory
(Elsevier B.V., 2008-09-01)
We study the two-alpha-particle (alpha alpha) system in an Effective Field Theory (EFT) for halo-like systems. We propose a power Counting that incorporates the subtle interplay of strong and electromagnetic forces leading ...
